The **M8RS-044-R** is a high-performance, precision magnetic sensor typically utilized in industrial automation and automotive applications. It is designed to detect magnetic fields with high sensitivity and reliability. ### 1. Technical Specifications Below are the general electronic characteristics associated with the M8RS series: | Parameter | Specification | | :--- | :--- | | **Housing Material** | Stainless Steel / Nickel-plated Brass | | **Mounting Type** | M8 Threaded (Flush/Non-flush) | | **Output Type** | Reed Switch / Magnetic Proximity | | **Contact Form** | Normally Open (NO) / SPST | | **Switching Voltage** | Up to 100V DC / 120V AC | | **Switching Current** | Max 0.5A | | **Response Time** | < 1.0 ms | --- ### 2. Key Electronic Components & Features #### A. Reed Switch Mechanism The core of the device is a **Reed Switch**, which consists of two ferromagnetic blades (reeds) hermetically sealed in a glass envelope. * **Action:** When a magnetic field (from a permanent magnet or electromagnet) approach, the blades become polarized and attract each other, closing the circuit. * **Durability:** Because the contacts are sealed in inert gas, they are resistant to oxidation and corrosion. #### B. Connection Interface The "R" suffix often denotes a specific termination type: * **Cable:** Usually a PVC or PUR jacketed cable with two or three wires. * **Internal Circuitry:** May include a protection diode or a varistor to prevent back-EMF spikes when switching inductive loads. #### C. Environmental Ruggedness * **IP Rating:** Typically rated **IP67**, meaning it is dust-tight and protected against water immersion. * **Shock/Vibration:** The solid-state internal mounting allows it to withstand high-vibration industrial environments. --- ### 3. Application Examples 1. **Cylinder Position Sensing:** Detecting the stroke position of pneumatic or hydraulic cylinders. 2. **Safety Interlocks:** Ensuring a machine guard or door is closed before operation. 3. **Pulse Counting:** Acting as a tachometer by sensing a rotating magnet on a shaft. --- ### 4.
